Answer:

80 units

Step-by-step explanation:

Area of trapezoid: a+b/ 2 * H

a = top, b= bottom, H = height

6+14/2 * 8

20/2 *8

10*8

80

Answer:

20

Step-by-step explanation:

To find area using coordinates, you would take the y-value of the first coordinate and the x-value of the second coordinate and multiply them. Then, take the x-value of the first coordinate and multiply it with the second y-coordinate. Take the second number and subtract it from the first number. for multiple coordinates, you would multiply the first and the second, the second and the third, and so on. Once you reach the last coordinate, just multiply it by the first again. then, take all of the numbers, from multiplying your coordinates and add them together and divide them by 2 to find your area.

We would start with coordinate (8,1) here because it's letter variable is W, which is first of the others alphabetically.

(8,1) (1,1)

1 x 1 = 1

8 x 1 = 8

1 - 8 = -7

next coordinate:

(1,1) (2,5)

1 x 2 = 2

1 x 5 = 5

2 - 5 = -3

next:

(2,5) (5,5)

5 x 5 = 25

2 x 5 = 10

25 - 10 = 15

next:

(5,5) (8,1)

5 x 5 = 40

5 x 1 = 5

40 - 5 = 35

-7 - 3 + 15 + 35 = 40

40/2 = 20

Answer:

x = 13

Angle 1 = 150 degrees

Angle 8 = 30 degrees

Step-by-step explanation:

11x + 7 + x + 17 = 180

12x + 24 = 180

12x = 180 - 24

12x = 156

x = 13

11(13) + 7 = 150

(13) + 17 = 30

The co-interior angles are solved and x = 13

The measure of angle 1 = 150°

The measure of angle 1 = 30°

Given data:

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line.

Alternate angles are equal

Corresponding angles are equal

Co-interior angles add up to 180°

The angles 1 and 8 are co-interior angles.

So, 11x + 7 + x + 17 = 180

12x + 24 = 180

12x = 180 - 24

12x = 156

x = 13

So, the measure of angle 1 = 11(13) + 7 = 150°

The measure of angle 8 = (13) + 17 = 30°

Hence , the parallel lines are solved.

The complete question is attached below:

In the picture above, parallel lines p and q are cut by transversal line t. If the measure of angle 1 is 11x+7 and the measure of angle 8 is x+17, then x is equal to and the measure of angle 1 is degrees. The measure of angle 8 is degrees.

Answer:

D x>-3

Step-by-step explanation:

3(-x+2) < 15

-3x + 6< 15 (Subtract 6 from both sides)

-3x < 9 (Divide 3 on both sides)

x>-3 (Flip the inequality because the variable was negative)

Answer:

Equation of a circle:

radius = the sq. rt of (x - h)^2 + (y - k)^2

Plug in the values for the center of a circle and the radius:

15 = the sq. rt of (x + 9)^2 + (y + 4)^2

(x + 9)^2 + (y + 4)^2 = 225

The answer is A or the first one.

Answer: | t- 98.6 | ≤ 3

Temperatures less than  95.6 and higher than 101.6 will be considered unhealthy.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality

.

| t- 98.6 | ≤ 3

Where t is the body temperature.

The absolute value inequality has 2 solutions:

1st solution

t-98.6≤ 3

t ≤ 3+98.6

t≤ 101.6

2nd solution

-(t-98.6) ≤ 3

-t+98.6 ≤ 3

98.6-3 ≤ t

95.6≤ t

Both:

95.6≤ t ≤ 101.6

Temperatures less than 95.6 and higher than 101.6 will be considered unhealthy.

Answer:

(6,0)

Step-by-step explanation:

First, let's find the line. We can do that by using the slope-intercept form of a line which is y = mx + b where m and b are the slope and y-intercept respectively. We know b = -18 and we can find m by doing (-18 - 6) / (0 - 8) = -24 / -8 = 3. Therefore, the equation of the line is y = 3x - 18. To find the x-intercept, we'll set y equal to 0. We get 0 = 3x - 18 → 3x = 18 → x = 6. Therefore, the x-intercept is (6,0). Hope this helps!

Answer:

So we can first use the distance formula which is for 2 dimensional but seen as we're in 1 dimensions we dont have to use it. So we can just get the distance between them using a formula I made -

|a-d| = distance

So if we use that formula we can get that -7-(-2) = -7+2 = -5. Then take the absolute value which is 5.

If the mean is 4 then the missing number will be 2.

The mean is the average of all the data values present in the data set.

Mean=sum/number

Let the missing number be x in this way mean will be
